SUPPORT FOR MAPS OR CHARTS.

Application led September 14, 1925.

This invention relates to holders or supports for maps or the like, such as are wound on spring rollers, and more particularly to the provision of cases for holding the maps and means for mounting the cases in suitable racks, the cases and racks both being adapted to be supported on a wall, blackboard or the like.

The objects ot this invention are to provide an improved support for maps or the like which may be constructed at a reasonable cost and which will be particularly durable and eiiicient in operation; to provide a steel or metallic case with means for holding a map mounted on a. roller; to provide a rack for holding one or more of such cases; and in general to provide such an improved device as will be described more fully hereinafter. In the accompanying drawings, illustrating this invention;

Figure 1 is a front view;

Figure 2 is an end view;

Figure 3 is a rear view of one of the cases; and

Figure 4 is an end view of one of the cases.

In the particular form of the invention as shown in these drawings, the map or chart 6 is wound on a sprinfY roller 7 which has the usual round pin or trunnion 8 at one end and a flat pin 9 at the opposite end. This roller is carried in a case 10 which is open at the front but provided with a top 11, back 12, bottom 13, and ends 14 and 15. r1`he ilattened or angular pin 9 engages with a similarly shaped hole 16 in the end 15 which prevents it from turning. The pin 8 engages with a slot 17 in the end 15 and is held by a clip or detent 18. Ordinarily the rectangular end of a spring roller is tted into a slot but by having the rectangular end engaging with a similarly shaped hole, the maps may be more easily adjusted and when being placed in position are not apt to release the spring so that it will unwind as frequently occurs when the reverse or ordinary arrangement is used. Heretofore, tubular cases with detachable ends have been used for holding maps or rollers, but are objectionable on account of the difliculty of fitting the ends over the roller pins or trunnions, and are especially objectionable as the maps cannot be reached for repair. With my improved device, the flat or angular pin may be inserted directly in the hole 16 and there will be no liability of the spring becoming unwound when inserting the maps Serial No. 56,360.

and fastening the opposite end. In my map case the map may be instantly removed Without any tools whatever and may be rewound or replaced and put back again Without any difficulty.

These cases are preferably made of light steel and are provided with supporting loops or hangers 19, which are pivoted at 20 to the back 12 and have eyes 21 for engagement with the hooks or nails on a wall. V

The cases 10 are mounted in a rack 22, which is preferably formed of angularshaped top and bottom members 23 and 24 and end pieces 25. The end pieces have inwardly projecting strips 26 to form guideways for receiving the ends of the cases 10. Although these strips may be formed in any desired manner, they are preferably made integrally with the end pieces. The end pieces are also provided with spring catches 27 tor engagement with the ends of the Cases for holding them in position. The racks may be made to hold any desired number of cases which may be conveniently done by merely changing the end pieces 25 to provide more guideways for the cases. The rack 22 is also provided with loops or keepers 28 which are pivoted to the back at 29 and serve to hold the rack on nails or hooks on the wall. These keepers are preferably spaced the same as the keepers, on the cases so that the rack or the single cases may be held on the same pair of nails or hooks.

With my improved device, it will be seen that any desired number of maps or charts may be exhibited from a single rack or the several maps may be removed and exhibited separately, which is particularly advantageous when it is desired to show maps in different rooms as in different school rooms. It will also be noted that my improved device may be made in any size desired and changes may be made in details of construction without departing from the scope of my invention and therefore I do not wish to be limited to the precise arrangement shown and described, except as specified in the following claims in which I claim:

1. A. map case comprising a relatively long channel formed of sheet metal with the top projecting beyond the bottom and having rigid ends, one of said ends being provided with a hole of angular form for receiving the flat or angular pin of a map roller, the opposite end of the case having a slot therein for receiving the round pin of the map roller and a detent pivoted to the end for engagement With the pin to hold the same in operative position.

2. A rack for the purposes set forth, com- 5 prising angular top, bottom, and end members, the end members having integrally formed strips to provide guideways, map cases engaging With the guideways, catches for holding the cases in position, and hang- 10 ers secured to the rack.

3. A support for maps or the like comprising a rack formed of relatively light sheet metal and having angular shaped top and bottom members and end pieces, said end pieces having inwardly projecting strips to form a plurality of guideways, map cases adapted to engage with said gnidevvays, each of said cases being formed of light sheet metal and having means at the ends thereof for receiving and operatively supporting the ends of a map roller, and means for holding the cases in position in the guideways.
